An excellent expandable at a reasonable price. If you study the geometry of the blades and the point, you will see that the blades will open very rapidly upon impact with your game. Very sharp blades, with what I consider a good all around cutting diameter; large enough, but not too large for bows without tons of kinetic energy. I also like the use of O-rings much better than rubber bands or the friction design used on Spitfires. The only down side is that the blades will bite into arrow inserts upon deployment, but that is the case with a number of mechanical heads. With all of this said, I am generally a fixed blade man.
